The heart functions by pumping blood both to the lungs and to the systems of the body. To prevent blood from flowing backwards or "regurgitating" back into the heart, a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricul...
Heart valves are metabolically active, as is the aortic valve; the cusps contain blood vessels for oxygen supply and removal of metabolic waste. The vessels exist in a higher percentage in the basal third of the cusps; these vessels continue from the commissures to the portion of the free ed...
The heart valves work the same way as one-way valves in the plumbing of your home. They prevent blood from flowing in the wrong direction. Each valve has a set of flaps, called leaflets or cusps. The mitral valve has two leaflets; the others have three. The leaflets are attached to an...
